Abstract
The proposed filterless industrial vacuum cleaner is operated by compressed gas and is fitted with an ejector nozzle. It connects to an existing suction and filtering system and its vacuum tool or vacuum tube end can be stored in a storage unit when the unit is not in use.
Description
2~679 The invention relates to a device for extraction of vacuum-cleaned material by means of a propellant noz~le operated by propellant, which has on the suction side a vacuum tube with vacuum tool on the end for extraction of the vacuum-cleaned material and on the discharge side is connected to a waste air pipe leading to asuction and filtering system.

r A, l Industrial companies generally use mobile industrial vacuum cleaners.

A suction fan - on the clean air side, i.e. operating behind the filter - generates the necessary vacuum pressure and the suction volume.
Drawbacks of industrial vacuum cleaners are their limited filter surface, leading to more frequent cleaning and changes, the high expense locally of obtaining a vacuum cleaner and making it available to others in a clean condition after use, the bulkiness of these vacuum cleaners, and the hindrances this presents.
In addition, the vacuum cleaner emits air and thereby creates air turbulences that can swirl up dust.
These arguments and the generally low number of cleaners present in a factory explain the frequent lack of vvce~a, Ive of the industrial vacuum cleaner in factories.

A device of the type mentioned at the outset is described in DE 37 17 569 C1. Inorder to remove vacuum-cleaned materiai via the vacuum tool or a vacuum tube connected to the latter, the vacuum tube leads either to a fan or to a Venturi nozle from which extends a co~ ssed air line for supplying propellant and capable of being shut off to the required extent by a cock.
To make use of the known device, not only the vacuum tool but aiso either a special switch for the fan or the cock for the propellant gas supplied to the Venturi nozle must be operated.
The object underlying the present invention is to design a device of the type mentioned at the outset such that problem-free handling is assured, in particular that an operation of the propellant nozle is possib!e by operation of the vacuum toolwithout additional manipulation being necessary.
The object is attained in accordance with the invention in that means are provided that automatically trigger a function switching on the propellant nozle when thevacuum tool is removed from its rest position and that automatically trigger a function switching off the propellant nozzle when the vacuum tool is placed in its rest position.
By the teachings in accordance with the invention, a compact device for extraction of vacuum-cleaned material is provided that virtually permits one-hand operation, since simply picking up or replacing the vacuum tool supplies or shuts off propellant gas to / from the propellant nozle. In particular, no additional units such as valves or fans are necessary for removing the vacuum-cleaned material. This in turn means that the device is easy to maintain.
Embodiments of the invention are described in the sub-claims.
The invention is described in greater detail on the basis of a design example to be found in the drawing.
In the sole Figure, a device 20 for extraction of vacuum-cleaned material by means of a propellant nozle operated by propellant gas is shown, for supplying the vacuum-cleaned material via said propellant nozle to a extraction pipe 9 that can lead to a filter system.
The nozle 1, which is a ring gap nozle, is connected via a pipe 4 to a vacuum tube 20.1 having the function of a vacuum tool 20 and having on the end a suction opening 8. The vacuum tool 20 / vacuum tube 20.1 with its suction opening 8 can be slid into a tool mounting into which projects a valve plunger 6 of a valve 5. Propellant gas flows via the valve 5 and a connection 10.1 to the gap 2 of the nozle 1 in order to extract vacuum-cleaned material when the vacuum tool is operated. The nozle 1is automatically opened when the vacuum tool 20 is taken out of the tool mounting 7.
Conversely, the valve 5 is closed by the pushing back of the valve plunger 6 when the vacuum tube 20.1 is slid into the opening 7.1 of the tool mounting 7.
The tube 3 leading from the valve 5 to the extraction pipe 9 opens into the latter such that the vacuum-cleaned material is blown inwards in the flow direction during operation.
Although in the ~IIlbo.li~ only one vacuum tool 20 is connected to the extraction pipe 9, in practice a number of vacuum tools can be connected to a single extraction pipe 9, such that the advantages achievable by the teachings in accordance with the invention are assured, these being among others:
- a vacuum tool costs only a ~raction of the price of an industrial vacuum cleaner, - installation is possible at the place where operation is required, - suspended assembly with a small attachment is possible, so that the vacuum tool does not get in the way.
